"WebApr 25, 2024 · States, like observables, are required to be gauge-invariant. A common point of confusion among QFT newcomers is the relationship between the state and the field variables, especially in QED where the spinor field is traditionally denoted $\psi$ — the same symbol that is also traditionally used for the state. These are not the same thing. " - State the postulates of crystal field theory
